A year ago, when an FBI agent told former SAC portfolio manager Mathew Martoma at his Florida home they had evidence he broke the law, he passed out in his front yard, the New York Times reported.

Last month, Martoma was arrested at his Boca Raton mansion and has been charged in what is believed to be "the most lucrative" insider trading scheme ever. Martoma worked at CR Intrinsic Investors, a subsidiary of SAC.
